JOHN E. CUMMINS, OF ARLINGTON, KENTUCKY.

GRAIN-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 274,468, dated March27, 1883.

Application filed January 10, 1883. (No model.)

To all whom it may concern Be it known that I, JOHN E. GUMmNs, a citi-Zen of the United-States, residing at Arlington,in the county of Ballardand State ot' Kentucky, have invented certain new and usefulImprovements in Grain Cleaners; and I do herebyl declare that thefollowing is a full, ciear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawings is an end View Vof my invention in elevation,and Fig. 2 a longitudinal vertical section of the same.

This invention relates to certaininew and useful improvements inmachines for cleansing grain, its object being to provide a de vice ot'this characterV whereby the smut, cheat, cockie, weevil, and otherimpurities may be thoroughly removed therefrom at one operation, andatthe same time separate the small and faulty kernels from the larger,thereby leaving the grain in the best possible condition for grinding.These objects I attain by the construction substantially as illustratedin the accompanying drawings and hereinafter described.

In lthe drawings, A represents a suitable frame or box provided with aremovable hood, B, said hood having arms B' upon its sides, which enterslots formed in the frame to support the'hood, and also admit of itsbeing de- Revolving within this frame and hood is the usual fan, C,having at one end of its shaft a small gear-wheel, a, meshing with alarger or driving gearwheel, D, provided with a beltpulley, b, overwhich passes a belt, c, operating a puiley, d, connected rigidly in anysuitable manner, either keyed or otherwise, to an inclined shaft, E, atthe lower end of theframe or box A. This shaft E is provided with radialarms e, having secured thereto and rotating therewith a suitable sieve,F, extending outwardly from one side of the frame or box a suitabledistance, and this extension pro tected by a cap, f, open upon itsunderside to allow the cleansed grain to fall into a receptacle placedthereunder.

The grain to be cleansed is placed in ahopper, Gr, set in the top of theframe or box,and its feed regulated by means of a slide, g, upon theinterior of said hopper. This hopper G is also Aprovided with anextension, lt, registering with and forming part of a chute H, throughlwhich the current of air caused by the rapid revolution of the fantinds its exit, carrying with it `the chaff, cheat, smut, and otherlight impurities as the grain descends from the hopper and falls throughan outlet, i, into an inclined spout, I, by which it finds its way intoa rotating sieve, F, a suitable screen, consisting of a series ot'fingers, Tr, extending upward into the chute at its outlet i -to thespout, said screen being in the form of a comb, so as to more readilycause the grain to fall into said spout and at the same time not impedethe blast from the fan. The grain, after entering the rotating sieve F,is separated from the cockle and other im purities not removed by theblast, and at the same time the small and faulty kernels are shook ontthrough the meshes oi' the sieve, while the larger ones pass out at theouter protected end thereof into a receptacleplaced there for theirreception, said grain being thus thoroughly cleansed of all impuritiesand imperfections and left inthe best possible condition for grinding atone operation, the machine being driven by a crank or other suitablepower.

Having now i'ully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a grain-cleaner, the chute H, having an outlet, t', and an interposedupwardly-extending screen, k, in combination with the frame or box A,hopper G, inclined spout I, sieve F,

and fan C, substantially as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
